Jikan Teishi de Yarihoudai in Pool

The main character of the hentai gets an incredible superpower "to subdue time". He decides to go to the local pool to test his abilities on girls. He chooses the two sexiest girls, Akane and Haruka, and uses the "time subduer" on them. The girls freeze in an instant, but when interacting with them, they could react and even make sounds. It wasn't quite a "time stop", one could say it was more like numbness... However, the hero no longer cared and didn't bother with these scientific terms, but enjoyed the process...
